How it works
Host, invite, play
Step 1
Host a private battle
Tap Host. We create a room that only your friend can enter.
Step 2
Invite by link or code
Copy the link or the six-character code and send it however you like.
Step 3
Play, straight-faced
Once you’re both ready, the round starts. First to break a smile loses a point.
Why Smile Battle
Private, friend-first, quick
Private by default
No random strangers. Every room is invite-only, with a friend you chose.
Two minutes to play
No lobby to browse, no waiting room to sit in — host or join and you’re in.
Free to play
Smile Battle doesn’t charge to host or join a battle.
Safety
Adult-only, and built to be reported
Smile Battle is for adults. Hosting or joining a battle requires confirming you’re 18 or older and accepting our current policies.
Every room is between you and someone you invited — never a stranger. Report and block are available from inside a battle at any time.
